Nutsedge control

I have a huge nutsedge problem in my garden. It’s growing all around my knock out roses, Purple Hearts and jasmine. Anything I can spray that won’t harm the other plants? I can’t keep up with it by pulling anymore.

We use a product called sedge hammer. Works well. Need to stay on top of applications. Relieve we bought from Amazon. I add in a little 2,4D to it as well.
But if it’s near other leafy plants I believe you’d be fine with just normal sedgehammer and apply liberally.

Glyphosate. Go to the co-op, Tractor Supply, Rural King, or buy it off Amazon. Don't buy Round-up. It isn't worth a damn anymore since they took the glyphosate out of it.
Just put a piece of scrap cardboard between your desirable plants and that damn nutsedge and soak it.
Also, don't pull nutsedge, ever. It encourages it to spread.

You can pull it if you get the nut out. I did it in my raised beds.

Halosulfuron - “Sedgehammer”

What about Image? The imazaquin version, not the atrazine one.
I have a widespread kylinga infestation and like the idea of the pre-mixed hose attachment kind.
(Kylinga is a close cousin to nutsedge)

Yes, imazaquin is listed/labeled for nutsedge control, and kyllinga. But in speaking with weed control scientists with the LSU AgCenter they tend favor halosulfuron for nutsedge control. But I’ve used imazaquin (bottle spray Image for nutsedge) with good success.

Thanks for the advice all. I’ll grab some and give that a shot.

Dismiss is another good product. Works faster than sledgehammer. Expensive though

I use Sedgehammer and it works beautifully for my nutsedge problems.
Edit: I didn’t know what killynga is so I looked it up. That’s exactly what I thought I was killing with Sedgehammer. It pops up all over my yard every year but the product wipes it out pretty well. It’s that fricking buttonweed that I can’t control without glyphosate.

If it’s completely out of control, use sedgehammer over Image. I’ve found both to be effective, but sedgehammer is better.
Shield your plants with a cardboard box, and you can handpick the nutsedge that’s in the plants. It’s much easier to get the root (nut) out of a garden than it is a lawn. It will grow back if you miss the nutlet, but you’ll eventually get it as they grow back quickly so you’ll have many attempts.
The nutlet may send out multiple shoots if you miss on the first shot, but it could help get the nut the next time by pulling both at the same time.
Don’t fret, everyone has/had this problem. And if you keep at it this year, you won’t have many next year and it’s very manageable.

Just be aware that mature weeds might require more than a single application for control, so if you don’t see the results after 3-4 weeks you are hoping for, spray again. And that applies to just about all herbicides.
Also, make sure you add surfactant to the spray solution. Ready to spray formulations and the small individual packets come with surfactant incorporated but not the general larger bottles with granular products. Read the entire label & follow instructions.

One not mentioned: Certainty. I have not used it but I know a lot of people who use Certainty and Celsius together in Bermuda lawns. I don't see roses listed on the tolerant ornamental plants though. Always try to look at the label for tolerance for ornamentals.
